How to get multiple choice biology quiz questions that match your course

A stack of old exam papers rarely lines up with the chapter your class is studying this week. DeckOwl reads your own notes, slides or textbook scans and writes multiple choice biology quiz questions based on that material, each with an explanation of why the right answer is right.

Example biology multiple choice quiz questions (cells and genetics)

Which organelle is the main site of ATP production in eukaryotic cells? A) Ribosome B) Mitochondrion C) Golgi apparatus D) LysosomeB) Mitochondrion. Oxidative phosphorylation in the mitochondria produces most of the cell's ATP.

Which molecule is the final electron acceptor in aerobic cellular respiration? A) Carbon dioxide B) Oxygen C) Pyruvate D) NADHB) Oxygen. It accepts electrons at the end of the electron transport chain and combines with hydrogen to form water.

During which phase of mitosis do sister chromatids separate? A) Prophase B) Metaphase C) Anaphase D) TelophaseC) Anaphase. The centromeres split and spindle fibers pull the sister chromatids toward opposite poles.

In DNA, which base pairs with adenine? A) Guanine B) Cytosine C) Thymine D) UracilC) Thymine. Adenine and thymine form two hydrogen bonds, while uracil replaces thymine only in RNA.

Which statement about enzymes is correct? A) They are used up in the reaction B) They lower activation energy C) They shift the reaction equilibrium D) They work best at any temperatureB) They lower activation energy. Enzymes are not consumed and do not change the equilibrium position of a reaction.

Built from your material

Questions come from the PDFs, slides, notes or page photos you upload, so they follow your course instead of a generic syllabus.

Explanations for every answer

Each question includes a short explanation of why the correct choice is right, so wrong answers become study moments.

Study in the browser or export

Practice on the free plan, or export to PDF, DOCX, Anki or CSV on a paid plan. Pro adds QTI 2.1 and Moodle XML for LMS quizzes.

How it works

Upload your biology notes

Add a PDF, DOCX, PPTX, plain text file or photos of pages. Photos are read with text recognition.

Choose the question type

Pick multiple choice, true/false or short answer, then generate your quiz.

Review and practice

Skim the questions, drop any that do not match your lecture, and study the explanations for the ones you miss.

Before you study, skim the set and remove any question that goes beyond what your instructor covered. Mixing in true/false and short answer items from the same source lets you check recognition of terms and also practice explaining processes like cellular respiration or DNA replication in your own words.

The free plan includes 3 generations per month and browser study. Exporting to PDF or DOCX requires Plus, and QTI 2.1 or Moodle XML export requires Pro, which helps if your instructor runs quizzes through an LMS.

Frequently asked questions

How many multiple choice questions should I write for a biology unit?

Aim for enough questions that each major concept appears at least twice across the unit. Start with chapters that have the most vocabulary and processes, since those usually need the most practice.

Are multiple choice questions good for studying biology?

They are good for checking recognition of terms and for catching confusion between similar ideas, such as mitosis and meiosis. Pair them with short answer questions so you also practice explaining how processes work.

Does the free plan let me export my quiz?

No. The free plan lets you study in the browser with 3 generations per month. Exports to PDF or DOCX require Plus, and QTI 2.1 or Moodle XML export requires Pro.

Can I use a photo of a textbook page?

Yes. Photos of pages are read with text recognition, so you can upload a picture of a chapter and generate questions from it.
